This course will present pragmatics within an overall program for studying language as a communication system, and is related to undertakings in all of the disciplines that contribute to cognitive science. We deal mainly with the extent to which language interpretation and production depends on language users’ reflexive assumptions and inferences about each other. Pragmatics is the study we rely on in order to elucidate the relevant assumptions and the logic in inferences. In other words, it is the study of how utterances have meanings in situations and is the study that explains why the use of a language is distinct from, but complementary to, the language itself seen as a formal system.
